Headspace solid-phase microextraction analysis of methyl isothiocyanate in wine.

摘要

Methyl isothiocyanate (MITC) is used as a soil fumigant for several vegetable diseases and as an antifermentative agent in wine. A new headspace solid phase microextraction (HS-SPME) method for analysis of MITC in wine is described. This method is fast, inexpensive and does not require any solvent. In addition, it shows a low minimum detectable limit and a wide linearity range. The quantification of MITC is performed by the standard additions method and does not require the use of an internal standard, as with other methods.
